Path of Blood Through The Heart

Heart Chambers and Valves Atria or Atrium Auricles Ventricles Interatrial Septum Interventricular septum Atrioventricular Orifice

Heart Chambers and Valves Atrioventricular Valve (A-V valve) Sulci Atrioventricular (coronary) Sulcus Interventricular Sulci Tricuspid Valve Chordae Tendineae Papillary Muscles

Heart Chambers and Valves Pulmonary Trunk Pulmonary Arteries Pulmonary Valve (pulmonary semilunar valve) Pulmonary Veins Bicuspid Valve (mitral valve) Aorta Aortic Valve (aortic semilunar valve)

Skeleton of the Heart Fibrous rings with other masses of dense connective tissue found in part of the septum between the ventricles that make the skeleton of the heart. Provide firm attachments for the heart valves Prevents the outlets of the atria and ventricles from dilating during contraction.

Path of Blood Blood from systemic circuit Superior Vena Cava and Coronary Sinus Right Atrium Right Ventricle

Alveolar Capillaries (lungs) Path of Blood cont. Pulmonary Trunk Pulmonary Arteries Alveolar Capillaries (lungs) Pulmonary Veins

Blood to systemic circuit Path of Blood cont. Left Atrium Left Ventricle Aorta Blood to systemic circuit

Blood Supply to the Heart Aorta Coronary Arteries Left coronary arteries Circumflex artery Anterior interventricular artery (left anterior descending artery) Right coronary arteries Posterior interventricular artery Marginal artery Peak Blood Flow
